Buffer system malfunction message means what? A) The label is cut off B) The Buffer system is too tension C) The label is not properly fixed on the web guilder D) None of the above The point at which the label is cut off from the buffer there will be buffer system malfunction on the HMI(human machine interface)
When monitoring three alarm comes on, it means A) Missing label at the vacuum cylinder B) Untransferred label at the vacuum cylinder C) Label not properly positioned on the bottle D) Option A and C On the labeller machine, one error that is usually displayed on the HMI when three alarm comes on is label carryover also called Untransferred label at the vacuum cylinder
When monitoring two alarm comes on, it means A) No label on the vacuum cylinder B) Label on the vacuum cylinder C) Missing label between cutter drum and glue roller D) None of the above When monitoring two alarm comes on, it means missing label between cutter drum and glue roller
When you have chips of label on the cutting station, what can cause it? A) The knife is too out B) Excessive vacuum C) The cutting point on the cutter drum is not correct D) The knife is too short Having chips of label on the cutting station can be caused by having excessive vacuum
Servo drive signal malfunction on cutting unit means? A) The rotary cutter servo motor is not running due to restriction B) Servo amplifier is faulty C) The interrupt card on the servo motor is faulty D) Servo amplifier is not faulty Servo drive signal malfunction on cutting unit means Servo amplifier is faulty
If the label on the cutter drum is either too early or too late to the suction rail. How do you address it? A) Adjust the cutter drum B) Adjust the rotary cutter C) Adjust the vacuum cylinder D) None of the above The vacuum cylinder should be adjusted. The moment the technical trained personnel notice that the label at the cutter drum is either too early or too late he/she should adjust the vacuum cylinder
What are the possibility for glue splash? A) Too much glue at the roller B) Viscosity of the glue is too low C) Viscosity of the glue is too high D) Less glue at the roller Option A is wrong. The reason for it is that having too much glue at the roller does not matter if there will be glue splash, the only thing that matters most is the viscosity of the glue. If the viscosity is too low there will be label carryover because the glue will be too thick to be supplied by the glue roller, they can solve this by increasing the heat temperature at the bowl. If the viscosity is too high there will be glue splash because at that state the glue is lighter than it should be. The correct answer is C.
What is bottle gap detection? A) There is gap on the infeed conveyor B) There is gap on the infeed worm C) There is missing bottle at the carousel D) There is no gap on the infeed conveyor Bottle gap detection means there is a missing bottle at the carousel.
What is the function of the web guilder? A) To level the label going to the feed roller B) To remove electrostatic paralises C) To determine the right length of label to feed in D) None of the above The function of the web guilder is to level the label going to the feed roller
How do you set the encoder back to zero position if it is out of reference point? A) Mechanical zero position turning the encoder at its direction of rotation until there is a rising edge B) Mechanical zero position turning the encoder at its direction of rotation until there is a falling edge C) Mechanical zero position and calibrate the encoder D) None of the above
How is synchronization achieved between the carousel and labelling station? A) Incremental encoder B) Sensor C) Absolute en-dat encoder D) Servo motor resolver
What is the purpose of the infeed worm timing belt A) Synchronize the infeed conveyor with the machine B) Synchronize the infeed worm with the machine C) Synchronize the infeed worm with the labelling station D) None of the above To Synchronize the infeed worm with the machine
When the rotary cutter is at the reference point, what is the angular value? A) 180 degrees B) 90 degrees C) 110 degrees D) None of the above
The central head is hooking on the top cam and thereby causing an unusual noise, what are the possibilities? A) Wear and tear of the centering bolt and pressure spring B) Over tension of the pressure spring C) cam follower too tight D) Cam follower not too tight Wear and tear of the centering bolt and pressure spring

This is the right webpage for anyone who hopes to understand this topic. You realize so much its almost tough to argue with you (not that I actually will need toÖHaHa). You certainly put a brand new spin on a subject that has been discussed for many years. Excellent stuff, just wonderful!
